TRIAX Multimedia Main Catalogue

Technical appendix
1. Basic technical requirements
All equipment and components in this catalogue meet, unless
otherwise stated, the European standards for “Cable networks
for television signals, sound signals and interactive services”
from the standardization organization CENELEC, which have
been adopted in national versions.
EN 50083-1 Safety requirements
EN 50083-1/A1
EN 50083-1/A2
EN 50083-2 Electromagnetic compatibility (EMC)
of equipment
The equipment conforms to the uniform European “EMC
directive” in accordance with legal requirements. For the majority
of the product groups in this catalogue, EN 50083-2
is relevant. In relation to the “Low voltage directive”, EN 60065
is the basis to which reference is made in EN 50083-1
“Safety requirements”.
The CE marking for products in relation to EMC and the low
voltage directive is based on these standards.
In addition, CENELEC committee TC 209 has ratified European
standards for equipment and system requirements for “Cable
networks for television signals, sound signals and interactive
services”.

System performance for return paths
The system and equipment requirements are matched to each
other in such a way that the minimum requirements for signal
quality at the subscriber’s outlet can be met with a minimum
of technical effort. In addition, requirements that result from
use of both analogue and digital signal transmission have also
been taken into account. The EN 50083 standards provide the
network operator, planner and installer with concrete
guidelines for network design and selection of appropriate
network components. Hirschmann network components are
developed to these standards and are marked in the catalogue
by the relevant EN standard. The equipment standards
(EN 50083 Parts 3...6) include fulfillment of the safety and EMC
requirements (EN 50083 Parts 1 + 2).
The legally required CE marking for antenna and
telecommunication products refers to adherence to
electromagnetic compatibility (EMC) limits and, from 1 Jan.
1997, to adherence to the low voltage directive.
The CE marking does thus not imply fulfilment of the product
and system requirements according to EN 50083- 3...-10.
For this reason Triax indicates compliance with these basic
requirements on equipment (EN 50083-3...6) by explicitly
noting the corresponding EN standard in the catalogue and in
the operating instructions.
1.1 Marking of components for TV cable networks
With the CE marking Triax confirms the compliance of its
products with the applicable EU directives (currently EMC and
low voltage directives) as well as with the standards EN 50083-
1, EN 50083-2 and EN 60065. For receivers the standards EN
55013, EN 55020 and EN 61000 are applied.
The CE marking is placed on the product, on the packaging
and/or included in the operating instructions.
To prevent interference between TV cable networks and radio
services, it is necessary to use components with sufficient
shielding. Due to the varying conditions in the European
countries, the shielding rate was defined in the European
standard EN 50083-2 in two stages, the high quality class A
and class B with reduced shielding rate values.
For example, the high radio density present in
many parts of the world makes the usage of class
A equipment necessary to prevent interactions,
particularly with safety-relevant radio services
such as air traffic control. As a differentiation in
the appearance of the equipment for trade and
installers is not possible, Triax and the other
companies in the Fachverband
Empfangsantennen- und Breitbandverteiltechnik
im Zentral verband Elektrotechnik- und
Elektroindustrie (ZVEI) e. V. mark the products
with the protected trademark-symbol shown.
In this way the higher quality of the equipment is
made clear.
(See 3.3 Shielding rate)
For compliance with the legal EMC requirements for TV cable
networks, we expressly recommend the usage of class A
components, including connecting cables so marked for
terminal equipment.
Protection class 2 according to IEC 60417-5172
for components with power connection 230 V ~.
